I agree. The only problem is when we get messages saying that something doesn't work and they neglect to say that they know better than the glibc devs and change the optimization. > for gcc, noOpt is needed, and for grub, I do not know, but it does not > hurt... It's kinda dumb to change optimization flags on GRUB. The execution time is negligible and any size changes are not significant. > Now, the opt_config file.
